Abstract
In the Pacific Northwest region, oaks are valuable species for their ecological role and attracting and supporting biodiversity in their areas of occurrence. In the Portland area, multiple agencies are interest on tracking individual occurrence for guiding restoration efforts. Today’s oak population is a consequence of historical forest landscapes and it testifies for population dynamics following local urbanization. In this study, I investigated the distribution and abundance of oaks on the Portland metropolitan area on the years of 1850 -1865. I used original Public Land Surveys to map trees distribution and abundance. The results of this study should foster conversations on oak population dynamics and provide historic framework for current ecological efforts on the Portland metropolitan urban ecosystem.
